Equal weights of methane and hydrogen are mixed in an empty container at `25^(@)C`. The fraction of the total pressure exerted by hydrogen is

A

`1/2`

B

`8/9`

C

`1/9`

D

`16/17`

Text Solution

Verified by Experts

The correct Answer is:

B

Pressure exerted by hydrogen will be proportional to its mole fraction.
Mole fraction of `H_(2)=2/(w/16+w/2)=8/9`
